Product Description:
The ZK1090-9191-0030 is a motor and data cable manufactured by Beckhoff for the ZK Motor Cables series. Designed for servo wiring in decentralized drive layouts, it combines Ethernet signaling with low-voltage supply conductors, allowing compact routing between a drive and a machine-mounted actuator. Within an automated cell, its purpose is to preserve signal integrity and mechanical flexibility so that motion commands reach the motor without timing errors.
The cable meets the Cat.5 transmission class, so it supports 100 Mb/s real-time fieldbus traffic while limiting crosstalk through a balanced 4 x 2 x AWG26 pair structure. Its molded length of 3.00 m fits short point-to-point drops inside a cabinet. Each copper core has a cross-section of 0.14 mm², giving a DC loop resistance of 280 Ω/km, a parameter that defines voltage loss over distance. The polyethylene insulation and overall polyurethane jacket provide oil and abrasion protection, while the eight contacts inside the straight RJ45 male plugs are arranged in an 8-pin format for standard Ethernet pin-outs. Data quality is further protected by a mutual capacitance of 51 pF/m at 1 kHz, keeping impedance nearly constant across the operating frequency band and ensuring deterministic network timing under servo load changes.
Signal delay is specified at 5.08 ns/m, so the fixed length introduces only 15 ns of latency. A braided and foil shield covers 90 % of the cable circumference, attenuating external EMI that could disturb the drive encoder feedback. For power carry-through, the core dielectric withstands a cable voltage of 60 V, while each plug is cleared for 1 A at 50 °C and up to 160 V, preventing arcing when the connection is cycled during maintenance. These electrical margins, together with the connector geometry and shielding, round out the dynamic behavior demanded by synchronized motion systems.
